Voiding order is not working, it is not changing the order state to void still showing submitted after pressing void item. Gift order is working
Void should make gift state Void and status should become New again so it prints to kitchen.
You post offers no detail. You say just not working!
Need more information.
Does any of those 3 actions happen. If not it is likely your issue is further up the automation trail, such as user mapping on the automation command button for void, possibly mapping on this rule.
PS, this will be a config mistake, not a bug with samba so have changed topic to a question untill which point a bug is actually diagnosed.
